Understanding VA Transformer Sizing

A VA transformer is a terminology used
in sizing the transformer. To understand the term you need to
understand the abbreviation. VA stands for

V = Voltage
A= Amperage

Calculation VA Transformer Power

If a VA transformer is rated at 120VA
it means that it can handle 120 volts at 1-ampere or 1 amp of current.
The VA is short for volt-ampere which is a designation of power.

All electrical devices come with a VA rated nameplate on them with
power usage. When you use a transformer to change voltage for
electrical equipment or for electric motors you need to take in
consideration the VA of the equipment. The load amps are always
calculated after the device is started and running. Most equipment has
a starting current, which is usually higher than the running mode.
When figuring the size of transformer you will need to multiply the
voltage times the load current and then multiply by 125 percent at
start up to factor in the load. Always use a little higher VA
capacity in the VA transformer that you select, never go with a
lower capacity VA transformer or you could damage your
equipment.

Sizing An Industrial Control VA
Transformer

When sizing an industrial
control transformer three characteristics of the load must be
determined in addition to the minimum voltage required to operate the
circuit. They are:
1.) Inrush VA – It is the volt-amperes that the VA transformers
must deliver upon initial start up of the control circuit. During this
inrush period the electromagnet control devices draws 3-10 times more
than normal current.

2.) Sealed VA – Total steady state sealed VA is the
volt-amperes that the VA transformer must deliver to the load for a
extended period of time.

3.) Inrush Load Power Factor
– This is difficult to determine without detailed vector analysis of
all of the load components, which such a analysis is often not
feasible. A safe assumption is 40% power factor. Twenty percent
was commonly used for transformer calculations but, recently tests
conducted on major brands of control devices indicated that it needed
to be higher.
